BACKGROUND: Subnasal lip lifts address perioral aging, but long-term quantitative data on postoperative changes and permanence remain limited.
OBJECTIVES: The aim of this study was to provide the first 3-dimensional (3D) evaluation of morphometric changes after subnasal lip lift ± autologous fat grafting over time.
METHODS: A retrospective cohort (2022-2025) of facial feminization patients undergoing subnasal lip lift ± fat grafting was analyzed. Standardized VECTRA 3D imaging measured philtral height, vermilion height and width, nasal base width, columella-labial angle, surface area, and lip volume preoperatively and at serial postoperative intervals. Early changes (3 months) were compared using t tests and longitudinal trajectories with linear mixed-effects models.
RESULTS: Forty patients were included (lip lift alone, n = 10; lip lift + fat grafting, n = 30). Both cohorts showed significant early philtral shortening (-2.92 ± 1.53 mm, P = .013 vs -5.95 ± 1.77 mm, P < .001) and increased upper vermilion surface area (1.40 ± 0.86 cm2, P = .022 vs 1.42 ± 1.23 cm2, P = .022). Fat grafting produced greater early volumetric augmentation (1.18 ± 0.86 vs 0.53 ± 0.25 cc), although between-group differences did not reach statistical significance. Mixed-effects modeling showed significant divergence in permanence. Philtral shortening showed 43% retention by 24 months (P = .003), whereas volumetric and surface area gains approached zero by 22 and 24 months, respectively.
CONCLUSIONS: There is measurable philtral shortening after subnasal lip lift. However, partial relengthening occurs over time. Additionally, early gains in vermilion display and lip volume decrease substantially by 2 years. Fat grafting enhances early augmentation but shows limited long-term retention.
